Time lapse photography is something I've wanted to try for a while.
But how exactly would I do it?
I've got an old digital camera lying about, a Fujifilm S602 zoom, that I could use. Of course I'd have to hook it up to the PC and get it to capture the images at regular intervals.
Again, how exactly would I do that?
A quick scour of Google revealed a couple of projects.
Finepix uses it's own kernel driver and it plugs into Video4Linux. I didn't get this to work initially.
I then found Mishoo's personal project to get his A310 capturing images.
This second one is much simpler and uses libusb to control the camera and it's a single binary.
Once I'd switched the camera into PC-Cam mode, it worked straight away. It had a few problems so I tidied it up a little and it now does something close to what I want.
Next steps... get it capturing decent images on a regular basis and then turning the photos into an AVI.
PS: It turns out that the power supply for my old Creative Zen MP3 player also works as DC-in for the S602 zoom.
Came to browse thru your updates as I've completely exhausted the technology news services for this planet, to this very minute, and was seeking other tech indulgences ;-)I saw your article on Linux, USB and camera's from March 11 .. and here I am, same day, wrapping up my work on UVC (USB's Universal Video Class) support in libMidnightCode;http://firstname.lastname@example.org/msg00845.htmlNeedless to say, anything that uses Video4Linux (v2) is piss easy to code for - I had not done it before this project. Just fopen the device, initialise it for your frame-rate, buffers, etc, read frames / write them to disk, and then close everything out. I wanted to do this for Project ATS (which requires directional motion video), and something much more basic for Project Discontent (which only requires single static frames for stop-motion animation). But it would be really easy to apply to time-delay/time-lapse video capture.If you're getting back into your C, you could code something up so that it fires via PHP triggers as they leave your events system ...ReplyDelete
